Binoculars
These come in all shapes and sizes, with prices ranging from £50 to £2000. They all do the same job, but are not equally effective. The top-range items are more likely to have crystal-clear images, HD glass and 100 per cent field of view for spectacle wearers. The Swarovski EL 32 (pictured left) offers a comfortable viewing experience and excellent image quality. However, for the casual observer who enjoys trekking or just sitting in their garden, a pocket binocular is ideal. For health and safety reasons, using binoculars with a magnification of more than 10x for a prolonged amount of time is not recommended
